What Travellers Say
Reviews Summary
Visitors are captivated by the magical views and the engineering marvel of the Kahuish Tunnel, one of the world's highest. The surrounding natural beauty, including Querococha Lagoon and its unique geological fault, adds to the allure. However, the extreme altitude poses a significant risk of sickness, and drivers must exercise caution due to poor visibility and sharp curves.
"Before and after entering the tunnel the views are magical... nature, its fauna, its flora are now all green around... I arrived early around 11 am, but from 1 pm the hailstorm and rain started... be careful... beautiful photos of the surroundings will come out... if you go through the tunnel use all your lights and honk your horn, I am already used to the mountains, that's why the altitude sickness doesn't bother me, but I saw several people fainted..."

"A unique spot, the tunnel that connects the Callejón de Huaylas and the Conchucos area, 4,516 meters above sea level, 900 meters long. If you visit this area, you'll find Querococha Lagoon on the route, a must-see. Also, look closely to the right side of the lagoon; you'll see a geological fault shaped like the map of Peru. And don't forget to visit the Chavín de Huantar archaeological complex."

"This tunnel is the ABRA or highest point to cross the mountain range on the way to Chavín de Huántar. Be careful because there is a curve just as you exit. Its location will be mentioned by the guides at the archaeological complex."

Navigating the High Altitude
When you do approach the tunnel, be aware of the symptoms of altitude sickness. If you or someone in your group starts feeling unwell, it's best to descend to a lower altitude as soon as possible. Many tours will have provisions for this, but if traveling independently, be prepared. The dramatic change in elevation can be disorienting, so a slow and steady approach to the high Andes is key for a safe and enjoyable experience.
Safety and Driving Considerations
Adding to the driving challenge is a sharp curve immediately after exiting the tunnel. This can catch drivers off guard, particularly if they are not familiar with the route or are traveling at speed. While the road is generally paved and signposted, traveler accounts highlight that recklessness can be a factor in accidents. Therefore, maintaining a safe speed, respecting all road signs, and being prepared for unexpected situations are paramount for a secure journey through this high-altitude pass.
The Scenic Route and Nearby Wonders
Adding to the scenic appeal is the Querococha Lagoon, a must-see located on the route. This picturesque lagoon holds a unique geological secret: on its right side, you can observe a fault line that has been naturally sculpted into the shape of the map of Peru. This natural wonder, combined with the expansive mountain vistas, makes the journey to and from the tunnel a visually rewarding experience, often considered a highlight by visitors.
